[Statins for elderly people, in primary prevention?]


[In a recent, retrospective cohort study, statin usage in primary prevention was found being not beneficial for patients (i) without diabetes over 75 years of age, and (ii) with diabetes over 85 years of age (75-84 years total mortality of diabetics was also lower). These findings are in sharp contrast to the two outstanding, double-blind, placebo controlled, randomized, a primary prevention studies done with rosuvastatin. Of these, 50% reduction in LDL-C in JUPITER was associated with a 50% reduction in risk and 25% reduction in LDL-C in HOPE-3 with 25% reduction in risk. Furthermore, subgroup analyzes did not indicate lower efficacy for the elderly. The recommendation of the European Atherosclerosis Society for primary preventions of the elderlies recommending consideration of statin use in these cases (Class IIa) is particularly relevant, especially in the presence of other risk factors such as hypertension. In the primary prevention lipid treatment, we can see quite clearly till 75 years of age and hopefully, we will even further after learning about the results of STAREE, a study that is designed to elderly and in which 40 mg atorvastatin is applied.]

[The importance of statin therapy in hypertension]

PARAGH György, PÁLL Dénes

[Hypertension and hypercholesterolaemia often co-occur and promote early cardiovascular disease. Previous studies have shown that antihypertensive treatment may be more effective if LDL cholesterol is also reduced. This may be due to the increased expression of angiotensin-1 receptor in hypercholesterolaemia, which increases peripheral vascular resistance through angiotensin-2, and adversely affects endothelial and smooth muscle cells. Other authors indicate that high cholesterol levels increase the production of angiotensin-2 through the activation of the chymase system. High cholesterol levels increase the amount of circulating oxidized LDL which binds to the transmembrane oxidized LDL receptor (LOX- 1) also activates the angiotensin-1 receptor. In addition, angiotensin-2 has an effect on intracellular cholesterol synthesis by enhancing the key enzyme of the synthesis of intracellular cholesterol, HMG-CoA reductase. The authors present the studies that support cholesterol lowering can contribute to lowering blood pressure and other major meta-analyses in which the beneficial effects of cholesterol lowering and lipid lowering on blood pressure reductions were not proven. In the background, it may well be that these studies are not designed to evaluate the effect of cholesterol-lowering drugs on hypertension in patients with hypercholesterolaemia, and non-statin-treated patients are not randomized.]

[Sexual problems in CKD – a narrative review]

TÖRÖK Marietta, JÖRGEN Hegbrant, GIOVANNI Strippoli

[Sexual dysfunction is highly prevalent in patients with CKD, especially those receiving dialysis. Given the high prevalence of sexual problems in CKD patients, there has been growing interest in finding effective treatments for sexual dysfunction. PDE5i and zinc have been found promising interventions for treating sexual dysfunction in men with CKD in a systematic review of RCTs, but the evidence supporting their routine use in CKD patients is limited. In the Collaborative Depression and Sexual Dysfunction (CDS) Study, over a cohort of 1611 men in hemodialysis, 83% reported erectile dysfunction and 47% reported severe erectile dysfunction, with depression strongly correlated to this problem. Similarly, sexual dysfunction was highly prevalent in women undergoing hemodialysis. Of the 659 respondents, 555 (84%) reported sexual dysfunction and more than half of sexually active women reported sexual dysfunction, associated with age, depressive symptoms, menopause, low serum albumin, and diuretic therapy.]

[COVID-19 and Parkinson’s disease]

TÓTH Adrián, TAKÁTS Annamária

[Parkinson’s disease is the elderly people’s condition which increases the risk of infections in the upper airways in its ad­vanced stages. Specific diseases (as hypertension, diabetes mellitus), older age and the male sex are significantly worsening the course of COVID-19. It would be challenging to examine parallel these diseases, since they are raising two important ques­tions. First, if Parkinson’s disease be a risk factor of COVID-19 morbidity and mortality. Se­condly, how the COVID-19 pandemic can influence the Parkinson’s disease patients. The authors are seeking answers to these questions based on the published results in the topic concerned.]

[Epilepsy in coronavirus pandemic]


[We aim to review the impact of COVID-19 pandemic on epilepsy and epilepsy-care. While the virus has no specific link with epilepsy, it may affect the nervous system both directly and indirectly, leading to seizures in several ways. The hyper-coagulable state occurring with the infection may cause strokes leading to seizures. The infection may first manifest in the form of disturbances of consciousness and behaviour, seizures, and even status epilepticus. The interactions of antiviral/antiepileptic drugs need to be taken into account during treatment. The hypercoagulable state induced by COVID-2 infection may cause stroke, which leads to seizures. The infection can occur also as an impaired consciousness of non-epileptic origin. Interactions of antiviral/antiepileptic drugs have also to be taken into account. The pandemic itself as well as quarantines and social distancing may cause anxiety and insomnia, challenge continuous antiepileptic supply; each one carrying the risk of seizing. Young epilepsy patients with learning disabilities and mental health issues are most vulnerable, justifying their hyper-protection. The danger of infection has highlighted the role of telemedicine. Internet-based video communication may ensure full care for chro­nic patients. Those methods favour bes­­ted patients with higher education. Epilepsy does not increase directly the risk of infection, but its comorbidities may worsen the course of the disease. Brain lesions and hypoxia, stress, insomnia and fever joining the infection increase seizure susceptibility. Because the danger of infection ma­de telemedicine an essential tool of pa­tient care, education and better computer supply for those in need is crucial. ]

[Role of Atrial Fibrillation in Stroke Prevalence: Implementation of CHA2DS2 – Vasc Risk Stratifi­cation Scale]

PAPP László, VIDA Nóra, BENGŐ Szilvia, KIS Tamás , GAÁL Gabriella, PETŐ Zsófia

[Introduction: Stroke is one of the leading causes of death and disability, therefore is an important public health concern. 20% of ischaemic cerebrovascular diseases are casued by cardiac-related embolism, wiith non-valvular atrial fibrillation (AF) as a major cause, and results in approximately 3-5-fold risk improvement. The aim of this study is to introduce the CHADS2-VASc scoring system, as an important tool in the estimation of stroke risk in AF patients. Recognition of AF and initiation of adequate therapy is a crucial step in the prevention of serious complications. The best-known indexes for AF’s vascular effects are HAS-BLED and CHADS2-VASc. According to European Society of Cardiology, CHADS2-VASc is recommended to use in every AF case with stroke risk, when direct anticoagulant therapy could be implemented. A nurse can work on stroke risk reduction among AF patients in various levels and competences. Primary prevention and health promotion is a responsibility for every health care worker, but at the same time, Advenced Practice Nurse could have a role either in diagnostics or initiating proper therapy.]

Clinical Neuroscience

CSÉCSEI Péter, VÁRNAI Réka, NAGY Lajos, KÉKI Sándor, MOLNÁR Tihamér, ILLÉS Zsolt, FARKAS Nelli, SZAPÁRY László

Background - Atrial fibrillation (AF) is the most common arrhythmia diagnosed in clinical practice. We aimed to measure the L-arginine pathway metabolites as well as their ratios in patients with different types of AF or sinus rhythm and to explore the relationship among the markers and clinical variables in the subacute phase of acute ischemic stroke (AIS). Methods - A total of 46 patients with AIS were prospectively enrolled. The patients were divided into three groups based on diagnosis of either sinus rhythm, paroxysmal or permanent AF. Plasma concentration of the L-arginine pathway metabolites were analyzed at post-stroke 24 hours in the three rhythm groups. Besides, clinical variables and laboratory data were recorded. Results - Asymmetric dimetylarginine (ADMA) was significantly higher in patients with permanent AF compared to sinus rhythm (p<0.001). Both ADMA (p<0.001) and symmetric dimethylarginine (SDMA) (p<0.002) at 24 hours were significantly higher among patients with permanent AF compared to those with paroxysmal AF. The L-arginine/SDMA (p<0.031) ratios at 24 hours were significantly higher among patients with sinus rhythm compared to those with permanent AF. ROC analysis also revealed that plasma SDMA cut-off level over 0.639 μmol/L discriminated permanent AF from paroxysmal AF or sinus rhythm with a 90.9% sensitivity and 77.1% specificity. Neutrophil-lymphocyte ratio also showed significantly higher value in individuals with both paroxysmal and permanent AF (p=0.029). Conclusions - Plasma level of SDMA could discriminate permanent from paroxysmal AF in the subacute phase of ischemic stroke. In addition, an increased neutrophil-lymphocyte ratio may suggest inflammatory process in the evolution of atrial fibrillation.

[Atrial fibrillation (PF) is the most common arrhythmia on the basis of analyzes conducted in different regions of the world. The main reason for this is the aging of the population. High blood pressure is one of the major factors of mortality in both developed and poor economical countries. The combined presence of the two diseases presents many hazards to our body. The most significant of these is the development of thromboembolic stroke, which is constantly increasing with age. The author analyzes in detail the aetiology called atrial cardiomyopathy, behind which there are complex structural, architectural, contractile and electro-physiological changes and leads to clinical manifestation of PF.]
